Abstract :
Aiming at the problem that different sections of the flight profile have different requirements on dynamic response and energy loss, by adjusting the rotating speed in steady state and the matrix R to make the system meet the requirement is put forward. The EHA-VPVM is modeled and simulated in the Matlab/Simulink and AMESim software. The simulation results show that the dynamic response and energy loss of system are determined by rotating speed in steady-state and the weighting coefficients of the displacement and the rotating speed of pump in the matrix R. The dynamic response becomes faster as the steady-state rotating speed increases, but the energy loss becomes more. It would improve the dynamic response when reducing the weighting coefficient of displacement in matrix R appropriately.
